摘　　要：目的:探讨oculyzer眼前节全景仪引导的准分子激光角膜磨镶术(laserin situ keratomileusis,LASIK)治疗远视及远视散光的临床疗效。方法:采用随机数字表法将患者55例110眼分为试验组和对照组。试验组应用oculyzer眼前节全景仪引导,进行个体化LASIK(25例50眼);对照组进行传统LASIK(30例60眼)。比较两组术后视力变化、屈光度变化、偏中心切削并发症的发生。结果:两组患者术后视力均明显提高,屈光度均有不同程度回退,试验组和对照组比较,试验组术后裸眼视力更好,6mo时屈光度更稳定,有显著统计学意义(P<0.05);试验组术后偏中心切削发生率明显少于对照组,有极显著统计学意义(P<0.01)。结论:Oculyzer眼前节全景仪引导的LASIK手术治疗远视散光的术后疗效更好,术后并发症更少。AIM：To evaluate the clinical effect of oculyzer-guided laser in situ keratomileusis （LASIK） and conventional LASlK on the correction of hyperopia and hypermetropic astigmatism. METHODS ：Totally 55 patients（110 eyes） were randomly divided into two groups. One group of 25 patients （50 eyes） were performed with oculyzer-guided customized LASlK, the other group of 30 patients （60 eyes） with conventional LASIK. Postoperative uncorrected visual acuity （ UCVA ）, refraction and decentered ablation complication were observed. RESULTS： The postoperative visual acuity of the two groups both improved significantly and the postoperative refraction regressed in varying degrees. In oculyzerguided customized LASIK group, the postoperative UCVA was better and the refraction at 6 months after operation was more reliable. There was statistical difference between the two groups（ P〈 0.05）. The incidence rate of postoperative decentered ablation in oculyzer-guided customized LASIK group was obviously less than that in conventional LASIK group and presented significantly statistical difference（ P〈 0.01 ）. CONCLUSION： Oculyzer-guided customized LASIK for hyperopia showed better visual acuity, less postoperative complication and was predictable.
